Abstract

This research focuses on the enhancement of the heat transfer in the concentric tube type of thermal energy storage (TES). The collective influence of the aspect ratio and number of fins is investigated. First, an optimal aspect ratio of the concentric tube TES is found. Additionally, then, the optimal number of fins is found. This combined optimal configuration of TES is then compared with concentric tube TES without. Liquid fraction of the combined optimal configuration was increased by 100% for case of charging as compared to TES without fins.

Summary

Introduction

Owing to the importance of thermal energy, engineers and scientists have worked tirelessly for centuries, trying to optimize the methods of producing thermal energy. Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. One of the solutions to many challenges related to thermal energy and its management is TES. It is of two types—sensible heat storage (SHS) and latent heat thermal energy storage (LHTES) [1,2,3].
